Some of you may know that my pistons rings took a crap on me and now I am in the process of tearing my motor down to get it built for more boost. I am only looking to do 15 psi as my daily driver, but I am also on a tight budget. I am planning on doing the build myself and was just wondering on what "HAS" to be done to achieve my goal of about 250 whp.

I just got a hold of 3s rods.
I will take my crank to the machine shop to get it turned down to accept the rods, but what pistons can I use?

Do I HAVE to get some sort of forged pistons to be able to boost 15 psi? Or can I just stick with the factory pistons with the forged factory 3s rods?

Now with the head and I am getting the head rebuilt with the cams regrind by Colt cams.

And I will for sure upgrade my fuel management. Why spend all this money on a build without upgrading the fuel management and timing. So I will for sure pick up the emanage ultimate.

My main concerns right now really is the pistons. Can I get away with stock pistons with upgraded pistons rings? Or am I better off spending an additional 600 for forged pistons?

If the crappy weather goes away, I will start tearing down the motor and this will be updated, BUT you guys will have to answer my questions first lol....

I am also concerned about my compression ratio? Because of the 3s rod length that will increase my compression, no? So will I need the forged pistons to lower the cp? Or can I just get a thicker head gasket.

if your rebuilding with boost in mind, get the forged pistons.
are they "needed" for 250whp, imo no, but they'll take alot more tuning mistakes than a factory piston will.
IIRC youcan get like CP pistons or somthing much cheaper than 600$ for a set, i would just call them, or weisco, or whoever, and see what they can do off the shelf for ya. i know chrisk from engine logics used to stock them, im sure mtbugges.com (MCS motorsports) would have them, or would know the best place to get them from.

Thanks Manny, I will look into this. Do you know if the stock pistons with the 3s rods will affect compression ratio?

you know, to be honest, im not really sure.
IIRC the 3s guys use the piston with the pin raised up a bit, but im not sure if you will need them, or somthing else. a bit of research over on mr2oc would give ya the answer you need im sure. if not, call mtbuggies. or chrisk (enginelogics)

will do.
